...uniformly curved surface. 2d. A real definition is a definition of a thing. Thus, a sphere is a volume bounded by a curved surface all the points of which are equally distant from a point within. 3d. A genetic definition is a definition exhibiting the mode of producing the thing. Thus, a sphere... | |
